I think you're confused. This is asking you to "delete profile" which is not your "account". All their screenshots say as much. You delete the profile from Chrome, not your Google account. Then you re-add your Google account as a profile in Chrome.
Please consider revising your comment because it probably causes more harm than good. Disclosure: I am in no way related to Videostream personally or professionally, I'm just a user who likes their products.
I have been having the same working/not working issues for the past 2 months. I've tried all the same troubleshooting steps mentioned and the only thing that seems to do the trick is a full reboot, both computer and my Samgsung SG4 phone.
This is very annoying because there doesn't seem to be anything changing on my Win7 system.
Can support give a full step-by-step process on what to do to get the VideoStream application to go back to normal operation without a reboot, and for god sakes, put it in a script that you can run easily from the Chrome-plugin if possible because the one embeded in the plugin sure hasn't fixed anything for me!
Include steps you can do with the Android App as well!
I'm finding that this and other streaming services do this with .mkv videos. They are squished. VLC player can stream now but it is a bit glitchy. I hope Videostream can fix the aspect ratio glitch with mkv files soon.
